Embodiment 1

[0026] Embodiment 1. This embodiment provides a method for measuring a CSCF entity in an IMS network, which includes the following steps:

[0027] Step 101, filter the message according to the first row of the data content of the UDP packet, and obtain three kinds of messages of INVITE, REGISTER and NOTIFY;

[0028] Step 102, judge whether the IMS message is a NOTIFY message, if so, then turn to step 103, if not, then this message is not processed;

[0029] Step 103, mark the source IP address of the NOTIFY message one by one as the S-CSCF entity, and add the non-repetitive IP address to the IP address list of the S-CSCF to be confirmed, such as figure 1 shown.

[0030] Step 104, mark the destination IP address of the NOTIFY message one by one as the P-CSCF entity, and add non-repetitive IP addresses in the IP address list of the P-CSCF, such as figure 1 shown;

[0031] Step 105, judge whether the IMS message is an INVITE message, if so, then turn to step 106, if not, then ...

Abstract

The invention relates to the technical field of communication network security, and especially relates to a CSCF (Call Session Control Function) entities measurement method for IMS (IP Multimedia Subsystem) network. The method comprises the following steps: filtering a message according to a first line of a data content of a UDP packet, and acquiring three kinds of messages, namely INVITE, REGISTER and NOTIFY; labeling source IP addresses of the NOTIFY message as an S-CSCF entity one by one, and adding unduplicated IP addresses to an IP address list of the S-CSCF to be confirmed; labeling destination IP addresses of the NOTIFY message as a P-CSCF entity one by one, and adding unduplicated IP addresses to an IP address list of the P-CSCF; verifying and confirming the S-CSCF entity through the INVITE message; and labeling an I-CSCF entity in the REGISTER message, and acquiring an IP address list of the I-CSCF. The CSCF entities measurement method for the IMS network provided by the invention automatically identifies different types of CSCF entities according to an IMS signaling flow, and obtains the IP address lists of three kinds of CSCF entities from the signaling flow, so that thesafety supervision efficiency of the IMS network is improved.

Description

technical field [0001] The invention relates to the technical field of communication network security, in particular to a method for measuring an IMS network CSCF entity. Background technique [0002] IMS (IP Multimedia Subsystem) is a network architecture that provides voice and multimedia services based on IP networks. IMS can realize the integration of fixed user services, mobile user services and Internet services, and multimedia services such as voice, data, and video. It is the core technology of the next generation network. [0003] In the IMS network architecture, CSCF (Call Session Control Function, call session control function) is the most important entity. According to different tasks, it can be divided into S-CSCF (Serving-CSCF, Serving Call Session Control Function), P-CSCF (Proxy-CSCF, Proxy Call Session Control Function), I-CSCF (Interrogating-CSCF, Inquiry Call Session Control Function) function) and so on. Since there are many types of IMS network entiti...
